Riverrailfan,
I was able to lay out a 4X8 version in SCARM using Fastrack, however, all of the curved sections were 036 45 degree with a straight section at the outer loop ends.
The sidings were way too short to fit any reasonable number of passenger cars.
The passing section where my station was to be placed was also very short.
After developing the expanded plan I deleted my 4X8 SCARM layout or I would be happy to share it with you.
